The biggest obstacle is complying with the restrictions of the rental bylaws of the HOA.

My biggest challenges have been getting the tenants used to my management style (much more rigid than the last owner), a nasty pest invasion and an immediate vacancy in the unit of a 6yr tenant who apparently had something against even basic cleaning.

The downside is that anyone can chime in, whether you approve of their opinion or not.I encourage you to recognize that not everyone will be in Harmony with your plans, ideas and conclusions.

One of my biggest regrets is not snatching up some of the opportunities that were brought to me that "didn't meet the company investment criteria."

I turned it down to sell the vacumes - probably my biggest mistake.

The downside is that you have to keep it all together between now and then.

The biggest misconception about wholesaling is that it is an easy way into real estate investing.

For me personally, I think the biggest pro is the flexibility - there's a lot you can do with mobile homes since they are in fact mobile.

My perspective on leverage, since I am in the business of leverage (broker/mortgage originator) is if I can reasonably control the down side and maximize the upside with the terms/rate/cost at which I am borrowing at, such as using a fixed 30 year, limited or no prepays, lower margins, non recourse, caps on adjustment periods, risk/equity share, etc I am okay with leveraging near maximum.For me it comes down to terms and cash flow as long as the risks can be minimized and the cash flow profit spread is high enough and stable enough even with stress tests (market drops rents go down XX%, business income goes down XX% or my personal income goes down XX% can I still debt service?)
